We stayed a week in the apartment and it was perfect for what we needed. The apartment was clean, well stocked, and very comfortable to live in. On arrival everything was spotless and there was plenty of essentials like laundry detergent, shampoo, etc. Check in was a breeze and much easier than other condos we have stayed at in the city.
As for amenities there is a pool and limited gym, fast wifi in the room, and a big couch with TV for relaxing. It was great to be able to come home and relax to after exploring Bangkok.
The apartment is near the Chong Nonsi BTS station which makes getting around the city very easy. Also very close to walk to Siam or any of the many streets with food as well.
Definitely recommend and actually tried to extend our stay but it was already booked! Would stay again if in Bangkok.
